Migration from KDS2 to KDS3, link problem

dafodil — Wed, 27 May 2015 06:45:20 GMT

Hi,

I try to compile a KDS2 project with KDS3. The project is with K64F, KDSK110, Processeur Expert and MQX RTCS, under Windows7, I followed this post Kinetis Design Studio: Migrating KDS V2.0.0 Projects to GNU Tools for ARM Embedded (Launchpad, KDS V3.0.0) very usefull.

but I got some problem to solve the error below, it seems to be a problem with Semihosting, not sure,

make -j4 all

I tried to add -specs=rdimon.specs and -specs=nosys.specs, I got same error messages.

Do you have any idea?

Hi Bernard,

I think this in the linker options is your problem:

-nostartfiles -nodefaultlibs -nostdlib -Xlinker -z -Xlinker muldefs -Xlinker -static

With this, you say that the linker should not use the default libraries and standard libraries: I suggest you try this:

Not sure why you have the additional -Xinker options, are they needed by MQX?

Hi Erich,

Yes, you are good.

I removed -nostartfiles -nodefaultlibs -nostdlib

and add -specs=rdimon.specs

I got no errors, cool.

I also experienced this after installing KDS3.0 alongside KDS2.0

After trying KDS3.0, all my projects in KDS2.0 workspace got those odd options, and failed to compile.

Also, the checkboxes you highlighted were not checked, but the -nostartfiles etc options were added directly to the text field on the Miscellaneous tab.
